FAQ
Q1: Is this cylinder liner kit a direct replacement for the original Weichai WP12 part? Yes, this kit is manufactured to OEM specifications and is a direct drop-in replacement for the original Weichai part number 612600080870. No modifications are required.
Q2: What is the recommended installation procedure for this liner? We recommend professional installation. Ensure the cylinder block bore is clean and free from debris. Apply a thin film of clean engine oil to the liner O-rings and bore before pressing in. Use a liner protrusion gauge to verify correct height (typically 0.02–0.10 mm above block deck).
Q3: How can I verify the correct fitment for my specific engine? Check your engine’s data plate for the exact WP12 model (e.g., WP12.375E40) and engine serial number. Cross-reference with our part number (612600080870). If uncertain, contact our technical support team with your engine details for confirmation.
